Cross-platform test management

When working with tests that run across multiple platforms (iOS, Android, etc.), ensure proper configuration and handling of platform-specific issues:

1. Place test files in all relevant platform-specific directories to ensure they’re properly recognized:

   metrics/linux-gcc8-release/render-tests/...
   ios-render-test-runner/...
   android-render-test-runner/...
   

2. When excluding a test that fails on specific platforms:
   • Document the reason for exclusion with a clear comment or issue link
   • Specify the exclusion only for affected platforms when possible
   • Create a follow-up issue to investigate and fix the root cause
3. For inconsistent test results that vary by device or environment:
   • Document the specific conditions where failures occur
   • Consider conditional test execution rather than complete exclusion

This approach maintains test coverage across platforms while providing clear documentation for temporarily disabled tests.
